annotations

问题 Background I am working on designing a file reading layer that can read delimited files and load it in a List . I have decided to use Spring Batch because it provides a lot of scalability options which I can leverage for different sets of files depending on their size. The requirement I want to design a generic Job API that can be used to read any delimited file. There should be a single Job structure that should be used for parsing every delimited file. For example, if the system needs to

问题 This question already has answers here : Required Attribute on Generic List Property (4 answers) Closed 7 years ago . I have this piece of code: [Required] public List<string> myStringList { get; set; } Unfortunatelly, it doesn't work, tha validator totally ignores it.
